Histiocytic necrotising lymphadenitis (Kikuchi-Fujimoto disease) in Saudi Arabia.

Abstract

Five cases of histiocytic necrotising lymphadenitis (Kikuchi-Fujimoto disease) are described. As the condition appears to be poorly recognised in Saudi Arabia, an extensive review of the histological features is presented, in order to improve pathologists' awareness and to minimise the risk of diagnosing prognostically less favourable conditions such as malignant lymphoma. Etiologic and pathogenetic features of the disease are also discussed.
